Used to inform somebody, usually via text message, that they are taking forever to do something. Using the abbreviation implies that you are becoming impatient, thus, can't be bothered with writing the full words out.

Pronounced (although there's no reason to say it out loud): eLM-lOh OR L-M-L-O

chatspeak for 'laughing my larynx out'. similar to LOL, ROTFL, and LMAO, but unlike in 'LMAO' and 'ROTFLMAO', the larynx, as opposed to the ass, has a connection to laughter, so although you couldn't laugh your larynx out any more than you could laugh your ass off, LMLO sounds better and doesn't contain any swear words.

Elaine: Did you see that new youtube video?
Audrey: The one with the unicorn? LMLO!!!!!
